I am still new to using Canvas. I wanted to try embedding material from an interactive polling site that I use with f2f classes. I have used the HTML editor to embed a widget that shows the results of the poll as they come in, but for some reason the HTML editor does not save the code to embed the widget that allows students to submit their answers. I have tried copy/paste numerous times and have tried typing in the code manually. I am not at all proficient with HTML but since I was able to successfully embed one widget, I'm not sure what I am doing wrong with the second. Any ideas why this isn't saving? The Content Page code is below; the code in bold is what will not save (the text and other widget save/display just fine).
